Amino Acid Sequence

Tyr-Pro-Phe-Phe-NH2

Descripción general

Endomorphin 2 is an endogenous ligand for μ-opioid receptor (MOR). It is a neuropeptide and has the sequence Tyr-Pro-Phe-Phe-NH2. It has a greater affinity for MOR1 receptor than MOR2. It resides in primary sensory afferent fibers, and might be the predominant ligand to regulate pain perception. In dynorphin-induced allodynia mice models, endomorphin has anti-allodynic effects. In tail flick test, it produces short-lived antinociception, which is naloxone-sensitive.

Acciones bioquímicas o fisiológicas

Potent, selective endogenous μ opioid receptor agonist.

Endomorphins were subjected to a number of structural modifications in a search for their bioactive conformations. The alicyclic beta-amino acids cis-(1 S,2 R)ACPC/ACHC, cis-(1 R,2 S)ACPC/ACHC, trans-(1 S,2 S)ACPC/ACHC, and trans-(1 R,2 R)ACPC/ACHC were introduced into endomorphins to examine the

The constitutional similarity with different secondary structure preference between the Aba-Gly and the spiro-Aba-Gly scaffolds were exploited to design the novel endomorphin-2 analogs Tyr-spiro-( R/ S)-Aba-Gly-Phe-NH(2) ( 1 and 2) and Tyr-( R/ S)-Aba-Gly-Phe-NH(2) ( 3 and 4). The (

The mu-opioid agonists endomorphin-1 (Tyr-Pro-Trp-Phe-NH(2)) and endomorphin-2 (Tyr-Pro-Phe-Phe-NH(2)) exhibit an extremely high selectivity for the mu-opioid receptor and thus represent a potential framework for modification into mu-antagonists. Here we report on the synthesis and biological evaluation of novel [d-2-Nal(4)]endomorphin-2 analogs

The recently isolated peptides endomorphin-1 and endomorphin-2 have been suggested to be the endogenous ligands for the mu receptor. In traditional opioid receptor binding assays in mouse brain homogenates, both endomorphin-1 and endomorphin-2 competed both mu1 and mu2 receptor sites

Endogenous mu-opioid receptor (MOR) selective peptides, endomorphin-1 (EM-1) and endomorphin-2 (EM-2), unlike so called 'typical opioids', are characterized by the presence of Pro(2) residue, which is a spacer connecting aromatic pharmacophoric residues. In order to investigate structural requirements for position
